Database connection resilience is the ability of the Integration Service to tolerate temporary network failures when connecting to a relational database or when the database becomes unavailable. The Integration Services is resilient to failures when it initializes the connection to the source or target database and when it reads data from or writes data to a database.
You configure the resilience retry period in the connection object. You can configure the retry period for source, target, SQL, and Lookup transformation database connections. When a network failure occurs or the source or target database becomes unavailable, the Integration Service attempts to reconnect for the amount of time configured for the connection retry period. If the Integration Service cannot reconnect to the database in the amount of time for the retry period, the session fails.
